Application filed February 15, 1912. Serial No. 677,838.

To all whom it may concern Be it known that we, Haws HERMANSEN and GnLiUs Anonnas Korono, subjects of the King of Denmark, residing, respectively, at Ringsted, Denmark, and Bernie, Denmark, have invented certain new and useful improvements in Machines for Producing lnterlccking Tiles of Cement, of which the following is a full, clear, and exact description.

The present invention relates to a machine for producing tiles of cement in which the cement mortar is automatically delivered from the filling hopper into molds traveling one behind the other underneath the same.

The principal object of our invention is to provide automatic means for cutting off mortar from a mass so that it can be formed into tiles or the like, such means being adjustable so as to cut off different quantities as required.

A further object of our invention is to provide means for compressing the raw material before the same hardens in a manner which will give the same efiect as hand Work.

At final object of our invention resides in the particular arrangement and combination of parts hereinafter described.

According to the invention, the hopper is provided on its underside with two plates connected with a slide which can be moved backward and forward and which accommodates the mold, which plates are placed one behind the other in the direction of motion of the slide and are mutually vertically displaced, corresponding to the amount of mortar to be conveyed, in such a manner that by one motion of the slide a layer is cut from the contents of the hopper and delivered into the mold and finally the hopper is completely closed. The machine embodying our invention also comprises a heater for compressing the mass delivered into the mold, said beater being suspended in front close to the crank of a crank shaft, and in the rear being suspended by means of a guide supported from a fixed shaft, by which the heater is controlled whereby the same performs a reciprocating sliding movement giving an effect similar to handwork.

An embodiment of our invention is shown in the accompanying drawings as an example.

In the drawing :Figure 1 is a side view of the machine. Fig. 2 is a section on line AA of Fig. 3. Fig. 3 is an end view of the machine and Fig. 4i is a section on line B-B of Fig. 1. Figs. 57 show details.

The frame of the machine consists of two vertical standards a and 6 connected by means of three sets of lon itudinally extending girders a, (Z, and e, the girders a carrying bearings for threeshafts f, g and h. The shaft f carries a pulley l and a gear 2 meshing with the toothed wheel 3 on the shaft g which latter also carries a small pulley 4 from which, by means of the belt 5 and the pulley 6, motion is transmitted to the crank shaft h. This shaft, by means of the connecting rod 7, is connected with one end of a sleigh or carrier 2' sliding on two guiding rails 8 arranged underneath the girders (Z. Upon these girders d are an ranged adjustable bearings for a crank shaft 7c serving for the operation of a beater c. ihe beater .2 consists of a metal plate (having a profile corresponding to that of the object which is to be produced), one end of which, directed toward the mortar container is pointed, while its other end is rounded. The shaft is is turned by means of the pulley 9, the belt 10 and the pulley 11 on the shaft f.

Figs. 5 and 6 show details regarding the beater 2. ihe same is partly suspended directly on the crank 70" and has further a guide Z in which the shaft 1 can slide for ward and backward. When the crank shaft is turned the shaft Z will slide forward and backward in the guide Z and the beater 2 will have imparted thereto an up and down, and a reciprocating movement in its guide, for pressing the mortar, etc, smoothly into the mold, leaving a smooth surface and preventing the mortar from sticking to the beater. By means of the adjustable bearlugs, the beater can i e adjusted above the mold for the desired thickness of the tiles intended to be produced and at the same time it is possible to regulate the pressure to be exerted and thereby also the density of the stone. T e girders cZ furthermore carry a polisher n pivotally arranged on a gudgeon which is also adjustable by means of screws.

The girders e carry three pairs of rollers 12 on which slides a form 0, the extreme rear end of which is connected with the upwardly directed end of the sleigh i which by a stay orthe like 7) is connected. also with the extreme front end of the frame 0. On the frame 0 is arranged a plate 7* and a plate 8 which latter is adjustable by means of screws or the like and carries in front an oblique plate 8. Over the frame 0 is placed a container 13 into which the cement mortar is filled, said container being connected to the frame a by means 01' a stay if or the line. The plate 2 closes the lowermost opening of ti e container when the slide in its outermost position. (Fig. The other 1, 1 v .1. plate a is situated somewhatin front about under the ea the plate r. the it' reuu obnque l, .o

'llhercby the cont lner so closed. The mortar ate is pushed into .c as the baclni'ard the obliq plate l 1 of 13 the mol d movement 8, by i; wljiich arrat l In tllront ot the ap uiratus is arranged a coloring device an consisting of a p int container 14: provided with a roller 15 and behind the se ne is arranged a brush 16, the bristles otl' hich glide over awip 17. The brush it revolved by means of a chain 18, one end of which connect d the frame 0, while the otl r end is secured a girder 4) connected with the SlGl JL i. The chain 18 thus moves forward. o, back" ard with the frame 0 and the sle 1 Between the chain wheel and brush is arranged a pawl and ratchet drive so that the brush 16 only allowed to turn in one direction.

Immediately in front Oil the polisher n is arranged a swinging l-znife y, the rear wardly directed arm 20 of which actuated by a pin 19 oil the pulley 6 that the knife g will be car.- 'ed down and will cut oil one tile of the row of tiles upon each revolution oil the pi. lfln front of the knife '3 rai'iged a lifter 91 which is pivoted to the frame and which, for each revolution, is lifted by the crank shaft 7a.

The machine operates in. the following is armanner :-Aii"'ter the container 15 ha been filled with cemen mm'tar. or the l the container M i h pai t, an

ron mold of the kind generally used in tl e in anu'hio ture of tile by hi. d is placed between the irder (Z FLU. in front of the sleigh 'i whereupon the machine is started. Upon the operation of the machine the mold is advanced for a distance which is equal to the length of one mold, hereafter the sleigh and at the same time the frame 0 are re turned. The plates 1* will. thereby cut oil a. layer of mortar from the container 13 whereupon said mortar slides down in the inclined plane 5 into the mold a3. Then another mold is placed on the girders d and through the subsequent forward movement of the sleigh the iron molds together with their loads, will successively move forward. Hereby the mortar in the molds will step by step advan e, and be carried under the aeater and the polisher a Before the mold reaches its position under the pcthe molded mortar will be sprinkled with cement and paint from the brusn 16. After the tile has been smoothed it is cut off from the row by means of the knife 1 whereafter it is lifted by the lifter 21 and exposed to hardening.

Having thus described our ini'enti on what we claim is 1. A machine for producing tiles and the like comprising in combination a hopper, a reciprocable plate normally closing said hopper at the bottom, a second plate mounted to reciprocate in unison with said first pl ate, said second mentioned plate being arranged at one side of and upon a lower plane than said first plate, whereby plastic material in the hopper will rest upon the second plate when the first one is withdrawn, and means for pushing material oil said second plate as said first plate returns to normal position.

2. A machine for producing iles and the like comprising in combination, a hopper, a reciprocable plate normally closing said hopper at the bottom, a second plate mounted to reciprocate in unison with said first plate, said second mentioned plate being arranged at one side of and upon a lower plane than said first plate whereby plastic material in the hopper will rest upon the second plate when the first one is withdrawn, means for pushing material off said second plate as said first plate returns to normal. position, and means for adjusting the vertical. distance between said plates.

In witness whereof, we have subscribed our signatures in the presence of two witnesses.
